I read it more as "here's a page I wrote and printed-out on my nephew's computer during the holidays" unserious rather "I'm joking serious". It's not a page in book of collected opinions Fed official keep, it's the cover page for the public release. Like, "this old thing? It's kind of out-of-date and unimportant but you can take a look if you want".

IE, there's a little effort to hide the significance of the document "in plain sight" here.
